英文摘要 | Quaternary sediments represent the main constituent which covers an ENE-WSW elongated depression some 25 km long and 10 km wide (Al-Ain area). This depression is encountered between two north and south low fault scarps and is located perpendicular to the Al Jaww plain and Jabel Hafit axes. Four main types of Quaternary surface deposits were identified belonging to: flood plain and braided channels; desert plain; aeolian sand; and sabkha. The first type shows many pedogenic and non-pedogenic features of which are dolocrete, calcrete and gypcrete. An ENE-WSW closely-spaced dip-slip, stepping pattern fault set could be traced in dolocretized-calcretized braided channel deposits, on the south margin of this depression, where the relationship between fault geometry, displacement and geomorphology suggest a model of either graben or half-graben. The role of this system in developing the landscape of Al-An is well documented near the surface but a comprehensive study to assess its role in the subsurface is needed.
